It could help you find a specific area that is failing. Then someone else might spot what's going on. :-) Would it help if you inserted some busy loops at interesting points in the code? I mean something like for (i = 0; i < 1000000; i++) for (j = 0; j < 1000000; j++) for (k = 0; k < 1000000; k++) { volatile int m = 0; m++; /*to keep the compiler from optimizing the loop away*/ } The wiki has information on where the code starts and the overall flow: http://www.coreboot.org/Developer_Manual#coreboot_Overview >From that you could place busy loops at strategic points to slow down the post codes. Can you get a serial console log? Ok, hope that helps. David
